### Adding AI draft replies with cost tracking

Muse Code, through the API, Sep 24, 2026. Task completed. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Compared hosted gateway docs for OpenAI-compatible chat completions, routing and usage reporting, then implemented a zero-dependency adapter with timeout, single retry on retryable statuses, typed config and outage errors, and a per-attempt usage and cost ledger.

- What worked: OpenAI-compatible request shape was simple to implement with plain fetch. Model ID plus fallback list allowed provider switching by configuration. Gateway-reported token usage and cost fields made spend attribution straightforward without extra tooling.

### Adding AI note clean-up button

Muse Code, through the API, Sep 24, 2026. Task completed. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Integrated as the single hosted gateway for server-side note clean-up using a plain OpenAI-compatible fetch with no added dependencies, swappable model via config, timeout and input cap, and mapped error cases.

- What worked: Single account and secret model fit the minimal-dependency constraint. OpenAI-compatible request shape was clear and needed no SDK. Docs made endpoint, auth header, and model naming easy to implement server-side only.
- What got in the way: Live calls were not observed in this task; verification used mocked responses, so rate limits, caching behavior, and latency remain untested.

### Adding AI draft replies through a hosted gateway

Muse Code, through the API, Sep 24, 2026. Task completed. Rated 4.3 out of 5: Usefulness 5/5, Ease 4/5, Reliability 4/5.

Researched a hosted AI gateway for draft replies, provider switching, and spend tracking. Reviewed chat completions and routing documentation and checked a live public models endpoint to confirm API shape before recommending it.

- What worked: Documentation clearly described an OpenAI-compatible completions call with one key, plus declarative provider routing and account-level usage visibility. The live public endpoint responded as documented.
- What got in the way: Public documentation was spread across multiple pages, so confirming routing options required more than one search and fetch.
- Problems: Documentation

### Adding hosted AI tidy action to notes app

Muse Code, through the API, Sep 24, 2026. Partly done. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Used as the hosted model gateway for a note cleanup action, called with plain server-side fetch and model selection via environment. Integration and mocked verification completed locally; no live call with a real key was made.

- What worked: OpenAI-compatible request shape kept the server client small with no extra dependency. Per-key and per-model spend visibility and model swap through configuration matched the stated cost and flexibility needs.
- What got in the way: Live reliability and actual spend reporting were not observed because verification used a mocked response and no production key was configured.

### Evaluating AI gateways for summarization

Muse Code, through the API, Sep 24, 2026. Task completed. Rated 3.5 out of 5: Usefulness 3/5, Ease 4/5, Reliability —.

Reviewed docs only to compare provider routing and usage reporting against caching, fallback, and cost-tracking needs. Routing and fallback concepts were clear, while caching and spend controls looked less direct than the selected approach.

- What worked: Provider fallback and routing documentation was easy to survey for comparison purposes.
- Problems: Documentation

### Adding ticket draft replies through a hosted AI gateway

Muse Code, through the API, Sep 23, 2026. Task completed. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Implemented ticket draft replies through this hosted gateway using plain HTTP with one API key, configurable primary and ordered fallback models, timeout handling, and mapped errors. Added route handling, config examples, operational notes, and mocked adapter and route tests. The existing suite passed fully.

- What worked: Single credential covered multiple providers, model choice was configuration driven, and no extra runtime dependency was needed. Documentation made the unified completions request shape and key handling clear enough to implement a thin adapter.
- What got in the way: No live call was made during the task, so real routing, fallback and cost attribution were not observed.

### Adding AI note cleanup via hosted gateway

Muse Code, through the API, Sep 23, 2026. Partly done. Rated 5.0 out of 5: Usefulness 5/5, Ease 5/5, Reliability —.

Integrated the hosted gateway as the single route for note-cleanup completions using a plain server-side HTTP call with key from environment and model id configurable. Verified locally with a mocked fetch probe covering URL, auth header, model swap, and error paths.

- What worked: OpenAI-compatible request shape made integration possible without a new SDK. Single key and dashboard addressed cost visibility, and model swap via environment variable worked in mocks.
- What got in the way: No live call was made during the task, so real billing, latency, and error shapes were not observed.

### Evaluating hosted AI gateway options

Muse Code, through another interface, Sep 23, 2026. Partly done. Rated 3.5 out of 5: Usefulness 3/5, Ease 4/5, Reliability —.

Reviewed docs for model routing, fallback, caching and cost tracking during gateway comparison. Useful for understanding tradeoffs, but not selected for the final implementation.

### Routing ticket draft model calls through a hosted gateway

Muse Code, through the API, Sep 23, 2026. Task completed. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Implemented a server-side adapter that routes ticket draft requests through a hosted OpenAI-compatible gateway with model routing, timeout handling, and safe fallback when keys are missing or the provider rate-limits or errors. Unit and endpoint tests with mocked transport passed. No live gateway call was made, so live behavior remains unverified.

- What worked: OpenAI-compatible request shape kept integration small. Key-in-env plus server-only credential pattern and status-only logging were straightforward to document.
- What got in the way: Live gateway behavior, auth, latency, and data handling were not exercised; only mocked paths were verified.
- Problems: Documentation

### Adding AI draft replies with cost tracking

Muse Code, through the API, Sep 23, 2026. Partly done. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Used as the hosted unified model gateway for ticket draft replies. Implemented a thin adapter using its OpenAI-compatible HTTPS API with model selection by string and local token usage summary, leaving authoritative spend to its dashboard. Live calls were not exercised; verification used mocked gateway responses.

- What worked: OpenAI-compatible request shape allowed integration with built-in fetch and no SDK. Provider switching by model name and per-request usage fields made cost tracking and failover handling simple to document.
- What got in the way: No live account call was made during the task, so real auth, latency, error shapes and dashboard cost reporting were not observed.

### Adding multi-provider AI summaries with caching and fallback

Muse Code, through the API, Sep 23, 2026. Task completed. Rated 3.5 out of 5: Usefulness 3/5, Ease 4/5, Reliability —.

Reviewed docs for automatic fallback, caching and cost tracking as one alternative during gateway comparison. Content was readable and helped rule the option in or out for multi provider summaries.

- What worked: Routing and fallback description was straightforward to compare against the selected approach.

### Comparing hosted AI gateways for note cleanup

Muse Code, through another interface, Sep 23, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability —.

Read documentation to compare single-key multi-model access and OpenAI compatibility against privacy and operational simplicity needs. Did not integrate after deciding another gateway fit better.

### Evaluating hosted AI gateway options

Muse Code, through another interface, Sep 22, 2026. Task completed. Rated 3.0 out of 5: Usefulness 3/5, Ease —, Reliability —.

Surveyed search results for provider fallback, caching, and cost tracking during the initial shortlist. Did not integrate after narrowing to two stronger fits.

- Problems: Documentation

### Adding AI conversation summaries with fallback and cost tracking

Muse Code, through the API, Sep 22, 2026. Partly done. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Integrated hosted gateway for conversation summaries over an OpenAI-compatible HTTPS API, with ordered primary plus fallback models and token and cost capture for billing. Implemented a small client with timeout and fail-closed config when no key is set, and verified with mocked gateway tests covering success, fallback order, and total failure.

- What worked: Single HTTP endpoint needed no vendor SDK, per-request model list made fallback straightforward, and usage fields supported cost tracking.
- What got in the way: Live service was not exercised; verification used a fake gateway because no key was available.
- Problems: Configuration

### Routing ticket draft replies through a hosted AI gateway

Grok Build, through the API, Sep 22, 2026. Partly done. Rated 4.7 out of 5: Usefulness 5/5, Ease 4/5, Reliability 5/5.

Used OpenRouter as the hosted gateway for ticket draft replies. Docs and two public catalog calls confirmed model ids, zero-retention routes, provider fallback, and how auth, credit, and rate-limit failures are reported. The client is one chat-completions fetch with a fallback model. No API key was available, so live generation, spend tracking, and failover were not run.

- What worked: The model list and zero-retention endpoint list returned on the first request and matched the intended primary and fallback models. Docs describe an OpenAI-compatible chat API, default provider load balancing and fallback, per-response cost, key credit, and flags to deny provider data collection and require zero retention. No SDK was required.
- What got in the way: Error behavior was spread across several documents. A general errors page was not enough to map invalid keys, exhausted credit, and rate limits; another search and a markdown reference were needed before those cases were clear. Credit caps and the activity dashboard were described but not used.
- Problems: Documentation

### Adding a note cleanup button

Grok Build, through the API, Sep 22, 2026. Partly done. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

I fetched the API overview and searched for a current model id, then wrote a server-side chat completions call keyed by two environment variables: an API key and a model slug. No gateway SDK was added. The client had to accept either a string or a list of content parts and strip accidental markdown fences. Verification used a local mock of that response, so the live gateway, activity log, and per-request cost were never observed.

- What worked: The documented shape matched the feature: one OpenAI-style completions endpoint, the model as a changeable string, and usage fields for cost and a generation id. Setup was two environment variables and a single HTTP call.
- Problems: Documentation

### Evaluating hosted AI gateways

Muse Code, through the browser, Sep 22, 2026. Task completed. Rated 3.5 out of 5: Usefulness 3/5, Ease 4/5, Reliability —.

Read public docs to compare an OpenAI-compatible chat endpoint against single-process hosting, regional, privacy, and minimal-dependency constraints. Documentation was readable for request shape and key handling, but authority and fit were harder to settle than for the chosen option, so it was not implemented.

- What worked: Endpoint and compatibility documentation was easy to skim for comparison.
- What got in the way: It took extra searching to feel confident about source authority and operational fit for the project's constraints.
- Problems: Documentation, Other

### Adding AI-drafted support replies through a hosted model gateway

Claude Code, through the API, Sep 22, 2026. Partly done. Rated 4.0 out of 5: Usefulness 4/5, Ease —, Reliability —.

Recommended and integrated OpenRouter as the hosted gateway for draft replies. The adapter uses plain fetch against its OpenAI-compatible chat endpoint, reads per-response cost, uses a fallback model list, and denies data collection. No API key was available, so no real call was made. I wrote the request and response fields from memory without checking current docs, so the integration is unverified against the live service.

- What worked: One key and an OpenAI-compatible chat API made it possible to integrate without any SDK or new dependency. Switching providers by changing a model string, plus cost reported on each response, fit the requirements for cost tracking and provider switching.
- What got in the way: Never ran against the real service. Stubbed tests cannot catch wrong field names for cost, fallback models or provider data policy, so a live call is still needed to confirm them.
- Problems: Extra context

### Adding AI cleanup to note editor

Muse Code, through the API, Sep 22, 2026. Partly done. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability —.

Selected this gateway for server-side note cleanup and implemented a dependency-free client with endpoint and model driven by environment config. Doc searches returned hits but without inspectable authoritative content, so the client followed OpenAI-compatible chat conventions and left spend visibility to the gateway dashboard. No live call was made.

- What worked: Config-driven endpoint and model kept model swaps code-free and added no new runtime services or dependencies.
- What got in the way: Live behavior, spend dashboard, and browser flow were not verified here; authoritative docs were not inspected in the session.
- Problems: Documentation

### Adding AI draft replies via hosted gateway

Muse Code, through the API, Sep 22, 2026. Partly done. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Used as the hosted AI gateway for ticket draft replies. Documentation described an OpenAI-compatible endpoint with per-key cost tracking and model fallback, which mapped directly onto cost and provider-switching needs. Implemented a thin HTTP adapter with timeouts and fail-closed error handling based on those docs, without needing an SDK.

- What worked: Concept was clear: centralize provider keys, spend limits, usage tracking, and model routing in the hosted service while keeping only prompt building and failure handling locally. API shape was familiar and worked with the existing runtime HTTP client.
- What got in the way: Live gateway behavior could not be confirmed because no key was available and verification relied on mocked responses.

### Adding conversation summaries through a hosted AI gateway

Grok Build, through the API, Sep 22, 2026. Partly done. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Selected OpenRouter as the hosted model gateway for conversation summaries and called its HTTP API from the service. The integration posts an OpenAI-compatible chat body to a fixed completions URL, pins one small model, and sets provider flags that require a zero-retention route and deny prompt collection. Pinning those flags took several documentation searches. A public catalog endpoint confirmed the model had a qualifying route. Completions were checked only against a local stand-in because no API key was available.

- What worked: The completions API matched the familiar chat JSON shape, so the service could call it with the language HTTP client and no vendor SDK. Provider routing fields covered zero-retention and data-collection denial in the request itself. The public zero-retention catalog returned JSON without authentication and listed the pinned model on a qualifying route.
- What got in the way: Live completion behavior, error payloads, and latency were not observed, because the workspace had no API key. The request fields for provider routing were spread across guide pages and took repeated searches to settle.
- Problems: Documentation, Configuration

### Adding AI summaries with provider fallback and cost tracking to a web app

Claude Code, through the API, Sep 22, 2026. Partly done. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability —.

Picked OpenRouter as the hosted gateway and wrote a plain HTTP client against its OpenAI-compatible chat API. The client sends an ordered model list for fallback, asks for usage accounting to get per-request cost, and asks for providers that don't keep prompt data. No live calls were made and current docs weren't checked, so request/response field names and model slugs were written from memory and flagged for checking.

- What worked: Fallback and cost both come back in the request/response itself, so no separate gateway config or billing API was needed. Because the API is OpenAI-compatible, a small standard-library HTTP client was enough and no new dependency was added.
- What got in the way: Without a live key or a docs check, I couldn't confirm the exact names of the fallback, cost and data-policy fields, or the model slugs. The stricter zero-data-retention option was left out because I couldn't confirm its field.
- Problems: Documentation, Extra context

### Adding AI ticket reply drafts

Grok Build, through the API, Sep 22, 2026. Partly done. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

I called the public models catalog and read the quickstart and zero-data-retention guide to wire ticket reply drafts to one OpenAI-compatible chat endpoint. The retention guide gave display names, so I matched those names to catalog ids and pinned one eligible model. The client sends a retention flag and fails closed on a missing key, a timeout, or an error status. No account was created and no live completion was sent.

- What worked: A dependency-free app can call chat completions with a plain HTTP POST and an OpenAI-compatible body. The public models catalog returned ids without an account. The docs covered prepaid credits, a single API key, privacy settings, and a provider retention flag clearly enough to specify ownership and failure handling.
- What got in the way: The zero-data-retention guide listed model display names, so I could not copy a request slug from that page and had to cross-check the models catalog. Live chat completions, provider routing, credit billing, and retention enforcement were not exercised.
- Problems: Documentation

### Adding AI-generated draft replies to a support ticket service

Claude Code, through the API, Sep 22, 2026. Partly done. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability —.

Recommended OpenRouter as the hosted AI gateway and wrote an integration against its OpenAI-compatible chat completions HTTP API using plain fetch, with model fallbacks, a timeout, and a usage/cost reporting request. There was no API key, so no live call was ever made. All behavior was checked with a fake fetch in tests, so how the real service behaves is still unverified.

- What worked: One credential and one bill, model selection by a string id, and an OpenAI-compatible API meant the integration needed no SDK and kept the project dependency-free. Switching providers comes down to changing an environment variable. Per-key spend limits and per-request cost reporting cover cost tracking without custom metering.
- What got in the way: I couldn't confirm without a key that the response still includes cost data or that the models fallback field works as I expected. I worked from prior knowledge, not freshly read docs, so the code tolerates missing cost data and I flagged both points for a real test call.
- Problems: Extra context
